3. Claims. (Cl. 189--62) y The present invention relates to louver window construction and specifically to the meansfor controlling the opening and closing thereof. v

vThe average louvered window construction consists of a multiple number of window panes, each held by suitable end framing With means for turning the end framing vto move the panes in positionof overlap or separation. The window panes are of the same size and generally the construction is such-as to maintain the window panes horizontally, although often times vertical panes are used. Such a construction, due to the number of Window panes, is usually heavy and as a result the means for operating the louvered windows is complicated, and likewise expensive to construct.

An object of my invention is to provide a louvered window construction which may utilize both for the window pane holder, as well as the' operating means therefor,

light weight metal stampings with resulting saving in thecost of manufacture.

A further object is the provision of louver window construction wherein the operating mechanism is concealed from view, thus improving' appearance.

-A further object is the provision of a louvered window construction so formed that individual panes of glass may be readily removed or inserted within the glass holders Without the necessity of dismantling the louvered window construction.

A further yobject is to provide a novel construction from light weight, soft aluminum stamping's'for individual actuator arms and glass holders and in such a manner that the two parts are held together for maximum shear strength and torque resistance.

My louver window construction employs side jambs which enclose, the operating mechanism for the window louvers. The construction is such that glass holders for ends of the glass panes or panels and the actuator means therefor have bearing engagement with a window jamb. The construction results in one thatvholds the window panels firmly and allows easy lmovement of the operating mechanism for turning the window panels without distortion or twist.

My operator assembly assumes perfect balance of the panes during openingand closing thereof even during adverse weather conditions.

FIGURE 6 is a side elevation, partly in fragment and in section, of a glass holder of the invention; and,

FIGURE 7 is a plan view of the actuator arm for the glass holder of 'FIGURE 6.

I have shown in FIGURE 1, in fragment, several panes or panels of glass 1, in overlapped position. Thesepanes or panels are adapted to be carried` at the ends of each pane or panel, and particularly at the operating ends thereofin glass holders, designated generally as 2. The glass holders are ordinarily known as clips. Each holder Z'is of channel form having a web or base 3 and two flanges 4 and 5. The flanges are substantially of the same length lalthough offset so that the end of flange `5, as shown at 6,

Other objects include a louvered window construction of few parts, easily assembled and generally superior to louver window constructions now known to the inventor.

With the above'y mentioned, and other objects in View, the invention consists in the novel and useful provision, formation, construction, association and relative arrangement of parts, members, and features, all as shown in one embodiment in the accompanying drawings, described generally and more particularly pointed out in the claims.

In the drawing:

@FIGURE 1 is a fragmentary front elevation showing several window panels incorporating the construction of the present invention;

FIGURE 2 is a fragmentary, partially sectional view, on an enlarged scale, taken on the line 2--2 of FIGURE 1;

IFIGURE 3 is a fragmentary elevation, on an enlarged of flange 3. The end portion 7 of flanged is bent at al slight angle toward flange 5 and the opposite end of flange 4 at 8 has a tab 10 at substantially right angular relation-y ship tothe ange 4. The end 6 of flange Sis bent inwardly at an obtuse angle as shown at 11. In forming the glass holder, the flange 5 is interrupted to provide a boss 12 which lies in the plane of the web 3. As shown in FIG- URE 6, a semi-circular portion to complete the boss lies beyond the web. The boss on its external surface which is the surface shown in FIGURE 6, is raised above the plane of the Web 3 and provided with a series of spaced apart parallel embossed ribs 13 and, likewise, provided at 14 with an annular vbearing rib surrounding the raised boss. The boss is formed with a central hole at 15. Thus, as shown in FIGURE 2, one end ofa glass pane is received within the glass holder or clip between the flanges, the upturned portion 111 and the tab 10 limiting end movement of the glass pane while the inwardly bent portions at 7 and 9 ybear against opposite sides of the pane to firmly hold the glass pane in the holder.

The actuating arm 20 has two portions 21 and22 in offset parallel relationship through the medium of an offset interconnecting wall I23. lPortion 2'1 is provided with an extruded boss 24 and portion 22 is provided with ernbossed parallel ribs 25 which are adapted to interlock with the ribs 1-3 of boss 12. Portion 22 is provided with a central opening at 26. Portion r21 of the arm 20 may be stilfened by depressing the same, as shown at 27.

The actuator end of each lpane or panel is supported by a jamb 30 of channel form. VThe jamb has avweb 31, a pair of parallel flanges 32 and 33 which terminate in fianges 34 and 35, the latter anges lying in the same plane, as shown in FIGURE 5. Flanges34 and 35 are spacedly provided with holes whereby the jamb may be secured within a window framing by means of screws passed through said holes. Depending upon the width of each panel'or pane, so Ithat the panes may overlap in closed position, as shown in FIGURE l, the web of the jamb lis provided With spaced holes 36. In this connection it is to be observed from FIGURE 5 that the web is provided with an elongated channel type rib 37 intermediate the flanges 32 and 33 which intermediate rib secures in the channel thereof a weatherstrip 38 which bears against the base of a holder 2, to provide a weather seal for the pane.

The raised boss 12 of a window holder 2 is passed through a hole 36 in the jamb 30 and an actuating arm is positioned within the jamb with the ribs 25 thereof interlocking with the ribs 13 of the boss 12, the boss 12 and actuating larm being secured together by a rivet or equivalent means 39. This positions the web of the jamb between the actuating arm portion 22 and the boss 12 of the window holder. It is noted that the diameters of the boss 12 and part 22 are greater than the diameter of hole 36 and that the annular rib 14 has bearing engagement with the web of the jamb. An operating bar ttl is that portion deinediby the rib 37 and the ange 32, and the. operating bar is provided with spaced holes 41, the holes of which receive'bosses 24 of the actuating l arms 20; 'Each boss 24 is held within a bore 4l of: the `operating bar when theribs of the boss 12 and the ribs 25 of portion-22 of ylan actuating arm is` heldi in cooperative relationship by the rivet 39.. l

The non-operator end of each pane or panel may have its glass holder held by la rivet and washer of suicient size and-shape to providea bearing surface on thek jamb. I have found .that my construction operates easily andl smoothly, is wear resistant, with no pants subject toV breakage. Tests that AI have run on the actuating arm and boss construction for the glass holder have shown that when'the boss and end 22, of the actuating-arm are f secured together, that the parts will not separate, b ut will resist all stress to the end that positive movement of the glass holders always resultswhen the actuating arms are moved by the operating bar 40. This has been one of the. difficulties which I have overcome by my which may exist kbetween an actuating arm and av glass holder. Such a drag has no effect on my construction. I have previously pointed out that glass panels may be easily received within the glass holders or removable therefrom due to the resilient end. s `Y To install my actuator assembly the link 56Y ispriveted support between aligned pairs thereof a' glass panel, .each glass holder being of channel form `and having a web and a pair of iianges, `the web of one of said glass Yholders s provided with an extended half round 'portionY extending beyond theflange andlying in the Lprlaneof the web, said extended portion andthe web formedl'withV a circular raised boss portion, the bossportion provided with'a' series of spaced parallel ribs,v` saidV raised boss 'portion adapted to .be received within a bearing opening of the janib, and
